Airlife KFU2-150
Ducted systems in the Airlife KFU2-150 series are designed for highly efficient purification and disinfection of air in supply and exhaust ventilation systems
add to cartDesigned for highly efficient purification and disinfection of air in supply and exhaust ventilation systems at medical institutions. The system eliminates all types of organic and inorganic pollutants from air, and destroys all types of microorganisms.
AIRLIFE KFU2-150 is used to purify and disinfect:
- supply air in clean medical rooms with standardized air contamination levels;
- supply air in clean rooms compliant with ISO Classes 3-8;
- exhaust air from infectious disease wards and tuberculosis dispensaries;
- exhaust air from chemical and microbiological laboratories that work with microorganisms from pathogenicity groups I to IV and that have a need to clean and disinfect air from biological and chemical pollutants, including chemical warfare agents, toxins, unpleasant odors, etc.
Main advantages:
- capture all types of liquid and solid aerosols and bioaerosols according to HEPA filtration grades E11–H14;
- inactivate any microorganism, including biological pollutants that cannot be inactivated by other methods;
- there is no selectivity in the destruction of viruses, bacteria and fungal spores;
- remove all types of organic and inorganic pollutants (unpleasant odors, formaldehyde, ozone, carbon monoxide, chlorine-containing compounds, etc.) from air;
- replaceable parts are disinfected during operation and do not require special disposal;
- low airflow resistance at high filtration grades (initially less than 160 Pa);
- connect to a common building management system and monitor all equipment parameters.

Pre-filter
The pre-filter arrests large particles of dust and litter, poplar fluff, animal fur and soot clots. The pre-filter protects the other filtering elements against early contamination.
Aerosol charger
The unit structure creates a symmetrical electrostatic field inside the element and 99.8% efficiency of charging of the aerosol particles sized from 0.1 to 100 μm at the linear airflow velocity of 3 m/s. The unit consists of cylindrical stainless steel elements with a tungsten electrode with a diameter of 17 μm in the centre.
As high voltage is supplied to the electrodes, the charger develops an electric field that charges all contaminating particles in the airflow.
During the electrostatic unit operation, some ozone is generated to inactivate all types of microorganisms and to oxidize the chemicals arrested by the subsequent filters. The ozone is not released from the purification device as it gets oxidized in the photocatalytic unit.
Barrier electrostatic НЕРА filter
Barrier electrostatic HEPA filter arrests aerosols, smokes and dust particles sized over 0.1 μm that may carry unpleasant odours, toxic chemicals and hazardous microorganisms. The developed technology allows using the polarized dust HEPA filter as a charged particle precipitator to achieve the HEPA H14 purification class at the minimum airflow resistance and impressive dust and oil arresting capacity. The solid, liquid, and biological aerosol arrestance efficiency of the filter is 99%.
The main advantages of the AIRLIFE barrier HEPA filter are high capacity, low airflow resistance and affordability.
Photocatalytic filters
In the photocatalysis process, all gas air pollutants (unpleasant odours, toxic gases, allergens, viruses, bacteria etc.) are adsorbed on the photocatalyst surface and mineralized to simple, harmless components (carbon dioxide, water and atmospheric nitrogen) as they are exposed to soft UV-radiation (diapason A). Instead of accumulating on the filter, the pollutants are fully decomposed, so that the photocatalytic filter regenerates during operation.
The photocatalytic filter inactivates all types of microorganisms and oxidizes the toxic chemicals, including the ozone that is generated in the electrostatic unit.
UV-A irradiation devices
Ultraviolet radiation activates the photocatalyst. In AIRLIFE air purifiers, the irradiation devices with the radiation diapason of 320-400 nm (UV-A diapason) are used; this is why the equipment can be used in the presence of people for an unlimited time. Due to the soft ultraviolet radiation, ozone is not generated.
Adsorption-catalytic filter
The adsorption-catalytic filter prevents the breakthrough of harmful substances during burst releases, as they are adsorbed on the surface of a catalytically active sorbent. The patented technology of a combination of the adsorption and photocatalytic filters keeps the sorbent catalytically active and regenerable in the operation process.
